    We study certain generalized Cauchy integral formulas for gradients of solutions to second order divergence form elliptic systems, which appeared in recent work by P. Auscher and A. Rosén. These are constructed through functional calculus and are in general beyond the scope of singular integrals. More precisely, we establish such Cauchy formulas for solutions u with gradient in weighted L_2(\R^{1+n}_+, t^{\alpha}dtdx) also in the case |\alpha|<1. In the end point cases \alpha= \pm 1, we show how to apply Carleson duality results by T. Hytönen and A. Rosén to establish such Cauchy formulas

    Astrophysical plasmas and fluids

    Full text link
    This book is a valuable introduction to astrophyscial plasmas and fluids for graduate students of astronomy preparing either for a research career in the field or just aspiring to achieve a decent degree of familiarity with 99% of the cosmos. The contents provide a true representation of the phenomenal diversity of dominant roles that plasmas and fluids play in the near and far reaches of the universe. The breadth of coverage of basic physical processes is a particularly attractive feature of this text book. By first using the Liouville equation to derive the kinetic, the two-fluid and single-fluid, descriptions of a plasma and a fluid, and then demonstrating the use of these descriptions for specific situations in the rest of the book, the author has probably chosen the most efficient way of handling this large technical subject. The two major astrophysical issues, fluid or plasma configurations and their radiative signatures, figure prominently througout the book. The problems are designed to give the reader a feel for the quantititative properties of celestial objects.Comment: 3 pages tex file

    Peer review of scholarly communication in health: Perspectives in the Internet age

    Get PDF
    Peer review is an established form of trust-marking and ensuring quality of scholarly communications. The advent of Internet has had its impact on peer review also. This paper examines the existing approaches of peer review utilizing the Internet. Future approaches, challenges and proposal of a framework for open peer review of directly published scholarly communication on the Internet is also discussed

    Cyber-pharmacies and emerging concerns on marketing drugs Online

    Get PDF
    The booming e-commerce and a regulation-less environment online have led to the rise of a new generation of websites that market drugs and other products over the Internet. Some of these drugs are often herbal products or of dubious quality, often marketed with a mix of professional design and unverified/fraudulent claims. Several concerns have arisen from different corners and evidence of malpractice has emerged. But there is a lack of sufficient evidence confirming the concerns

    Open, Online and Global: Benefits of BioMedical Journals Going Online and Open

    Get PDF
    The emergence of Internet affords the immense possibility for scientific publications to be indexed, linked, copied, archived, redistributed and searched at ease and at a lower production cost. This has paved the way for the emergence of Online-Only Journals like the Online Journal of Health and Allied Sciences. This has also spurred the rise of Open Access movements spearheaded by the Budapest Open Access Initiative and the Public Library of Science. 'Open Access' means immediate, permanent, toll-free, non-gerrymandered, online access to the full-text. Open Access can be considered as borne on three major pillars of Open Access Publishing, Open Access Archiving and Open Access Support and Open Access publishing is perhaps the future of scientific communicatio
